EV training my Xerneas for the "Enter the Dragon Type" competition.
I need 252 Special Attack EVs. I only have Power Lens as a booster for 4 more points in special attack.
Say I went to route 113 with a Oddish in my team to mass beat hordes.What is the equation of given Special attack points?
Does it follow:

Oddish Fainted gives 1 SpA point; Power Lens increases every individual's given points for a total of 25 EVs in special attack for a horde of 5 Oddish fainted?

Or Oddish Fainted gives 1 SpA point; the horde gives out 5 points for a total of 9 EVs for a horde of 5 oddish fainted?
